F1 Error Code in Whirlpool RB160, RB260, RB270, RB770, RF396, RM765, RM770, RS675, RS696 Series Ovens and Thermador RDDS30, RDF30, RDFS30, RDSS30, RED30, REF30, RES30, RSS30 Series Ovens

This article refers to a specific problem we’ve been encountering with two different types of oven control boards – the relevant model and part numbers can be found at the end of the article.

These control boards can throw F1 error codes in response to a variety of failures.  Often, these error codes are the result of bad power supply or logic control circuits that can be repaired at FixYourBoard.com.  However, we have been finding that even after a control board is rebuilt and passes a full function test, it still throws F1 when reinstalled in the original oven.  How can this be?

It turns out that these control boards connect to the platinum temperature sensing rods through wire nuts.  The connection in the wire nut is going high resistance, which causes the control board to think the oven cavity is over temperature…resulting in an F1 overheat error code.  This connection seems especially susceptible to temperature change as well, so this problem is especially apparent as you start heating the oven.

So, if you’ve had your board rebuilt by FixYourBoard.com or recently got the board replaced, and you’ve replaced the temperature sensor, but you’re still getting an F1, inspect these wire nuts!  The easiest way to find the wire nuts will be to follow the wiring with your hand (make sure the breaker is off) from the temperature sensor (or from the board if you know which wires go to the sensor).

You will likely find that the wiring inside the nut has rusted/corroded.  We recommend you cut off the already exposed portions of the wire and strip some insulation off, allowing “fresh” wire to be reconnected in a new wire nut.

Remember to have all your control board needs handled at FixYourBoard.com!

Thermador Built-In Oven – Takes Too Long to Heat, Can’t Control Temperature, No Heat

Does your Thermador oven have temperature control problems caused by the control board?  The following post describes the behavior of a properly working control board in pre-heat.  This applies to the following model series: SCD27,  SCD30,  SCE30,  SCE70,  SC272,  SC301,  SC302,  SMWS7,  SMW27,  SM272,  SVD48,  S272T,  S301T and  S302T.  At www.FixYourBoard.com, we hear about problems such as the oven taking too long to heat, temperature fluctuations in the oven, oven is burning food or there is no heat at all.

First, the picture below shows the relevant connections  that should be measured to ensure that the elements are correctly turned on by the relays.  This picture is an example of part 492067 which is the power / relay board.  Its purpose is to provide power to the oven, turn on heating elements and fans, and communicate with the display board.

Relay Board and Noted Measurement Points

These ovens can be tricky to troubleshoot, but start with the following table which shows how the timer is controlling the heating elements and cooling fans.  Note that an AC voltmeter must be used to perform the following checks

Thermador Oven Control Board 486752 / 14-33-347 – Door Lock Sequence and Errors

Are you having door lock problems with your Thermador control board 486752 or 14-33-347,  487604 or 316080103.   At www.FixYourBoard.com, we get questions about the door lock operation for this controller.  This post addresses this by describing the sequence of events when the controller is programmed for a clean cycle.    We hope this information will help you  troubleshoot door lock issues with the following model numbers: RDDS30, RDDS30QW, RDDS30V, RDDS30VQB, RDDS30VQB, RDDS30VRS, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS, RES30, RES30QB, RES30RS, RES30W, RDDS30, RDDS30QW, RDDS30, RDDS30V, RDDS30VQB, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS,  RES30,  RES30QB,  RES30RS,  RES30W.

State 1 -Clean Button Pressed and Time Set  (Door still unlocked)

Note that the blue display show that clean mode has been selected and the total time for the clean mode.  The state of the switches is shown in the diagram.  Pins 7 and 8 are shorted together with switch #1.  This is the un-locked state.

Thermador_486752_clean_start1

State 1 -Display As Soon as Clean Time is Programmed

State 2 – Automatic Door Locks are Running (One Second after State 1)

After a second in state 1, the following happens:

  1. The clean light comes on.
  2. Controller turns on the door lock motor.
  3. This state only last until motor releases switch 1 and pins 7 and 8 are no longer connected.

 

Thermador_486752_clean_start2

 

State 3 – Lock Motor Still Spinning and Switch #1 is Not Pressed anymore.

Pins 7, 8 and 9 are not connected and the motor is still spinning.

Note that the display shows the “locked” even though switch #2 is not pressed yet and door is not locked.  

 

Thermador_486752_clean_door_all_pins_open

 

State 4 – Lock Motor has Stopped Spinning Because Switch #2 shorted pin 7 to 9.  Oven has turned on the heating elements.

Note that the display now says “ON”.  This means that switch #2 was pressed by the lock motor which shorted pin 7 to 9.  The oven will now reach cleaning temperature.

 

Thermador_486752_clean_on

 

State 5 – Fault State.  If the controller does not sense the door lock on pins 7 and 9.

In this fault mode, the controller will beep and show door on the screen.

Thermador_486752_clean_door_error

Error State – Control did not receive the locked signal on pins 7 and 9.

How to Remove an Oven Control Board

If you own an oven, chances are at some point you will need to access the electronics behind the control panel.  Doing it yourself can save you some money and is easy to do on most ovens.  Regardless of what you may hear, the control boards on all appliances are repairable.  Many times, control board repair is the only option because they are obsolete or no longer available from the manufacturer.  A good example of a repair service company is www.FixYourBoard.com.

This posting shows the basic steps for removing a control board from a built-in electric Whirlpool model .  A similar process applies to Kitchenaid, GE, Thermador, Dacor, Jennair and many others. This process is just as easy on most other oven brands and once you do it, you will be glad you tackled the job.  All you usually need is a screw driver and a refreshing drink.  This post covers the basic steps that one should follow.

1.  Turn Off Power to Oven

This is the single most important step.  This is for your safety and to protect the electronics of the oven.  Removing power ensures that no wires will be shorted to other metal parts.   This is done with the circuit breaker.  Find the right one and make sure it turns off all lights in the oven and control panel.

2.  Remove Mounting Hardware

Front View Screw Locations

Side view of screws holding control panel

This whirlpool has mounting screws for the support brackets on the sides of the oven door.  These can be removed by opening the door and removing the holding screws.

3.  Take Notes and Pictures

Now, the control panel should be loose and you can pull it out to see what is behind the control panel.  This is great time to take some notes and pictures.  This is quick to do and you will glad you did once it is time to re-install the control board.

Behind Front Touchpad

In most cases as in this one, you will see the control board attached to the front panel.  Again, before you remove the control board from the panel or disconnect any wires, it is recommended that you take some snapshots before going any further.

Once the connections are removed and the control board is free, all you have to do is wrap it with some cushioning and put it in a box.  Most control boards will be fixed, tested and returned to your door step within a week.
